This could hardly be better: simple evidence of brains at work, and muscles too; tiny collections assembled and abandoned. A photographer haunts a university library; he spots and captures stacks of books.

The photographer writes of his first encounter with a noteworthy stack:

However, by dint of the peculiar juxtaposition, it seemed as though I happened upon the mineral tailings and spent fissile materials of a speculative research project born a few hours prior.

It’s totally enjoyable to click through the images, remembering that each one represents a real person’s migration through physical space; I think the wacky juxtapositions are therefore interesting — and occasionally melancholy? — in a way that, say, browser histories are not.
